Alongside originality, fixation must also be satisfied in order to be protected by copyright. Fixation, in the United States, is defined and required as per Title 17 of the
United States Code. As per 17 U.S.C. §101, fixation takes place in a work, "when its embodiment in a copy or phonorecord is sufficiently permanent or stable to permit it to be perceived, reproduced or otherwise communicated for a period of more than transitory duration." This definition is largely similar to the view taken in Canadian Admiral Corp v Diffusion Inc., though fixation in the US only requires the lower standard of "transitory duration" for copyrightable work whereas in Canada, fixation has been articulated as "more or less permanent endurance." The court also noted that in this instance, it was very difficult to determine at what point fixation had occurred. Demonstrating fixation can also be crucial in showing infringement. A work may be infringed by the creation of copies in violation of §106 of the United States Copyright Statute. It must be shown that infringing works are in a 'fixed' form constituting copies. As per 17 USC §101, in the case of both 'copies' and '
phonorecords', they are 'materials in which a work can be fixed by any method now known or later developed'. Owing to the use of the term 'transitory duration', the minimal threshold for duration has been the subject to instances of litigation in the
United States. Cartoon Network, LP v. CSC Holdings, Inc. is a prime example. This litigation involved the a cable network provider known as '
Cablevision' which offered a remote storage DVR technology for their viewers. It differed from ordinary DVR services in that instead of storing the content in the personal drive of the subscriber, the content was stored remotely at Cablevision's facilities. At multiple stages, the content was buffered in such a manner that programming content was held in the buffers for periods o.1 and 1.2 seconds at a time. The Circuit Court decision held that on account of the buffer period the duration requirement was not satisfied as the reproduction was only for a transitory duration. In the case of
sound recordings, fixation actually determines the scope of rights. According to 17 USC §114(b), the exclusive right of the copyright owner is restricted to duplication of the 'actual sound fixed in the recording' and this goes for the right to create derivative works as well. This excludes the imitation or simulation of the sounds in the copyrighted recording. In some cases, the fixation of the work may not be relevant to a claim of infringement. 17 U.S. Code §106 gives the copyright owner the exclusive right to prepare derivative works based on the copyrighted work. However, no requirement of fixation appears in the definitions of derivative works under 17 USC §101. Apart from this, fixation in the United States is relevant to the law on live performances as well. The law provides remedies in case of an unauthorized fixation in the sound or images of the live performance in a phonorecord or copy. == Fixation in material form under Indian copyright regime ==
